Density and Viscosity of the Ternary Systems [NMP][MSA] + LaCl₃ + H₂O, [NMP][BSA] + LaCl₃ + H₂O, and [NMP][p‑TSA] + LaCl₃ + H₂O at Different Temperatures and Atmospheric Pressure

The densities and viscosities are measured in the temperature range (293.15 to 308.15) K and atmospheric pressure for the ternary systems [NMP]­[MSA] (1-methyl-2-pyrrolidinonium methanesulfonate) + LaCl₃ (lanthanum chloride) + H₂O, [NMP]­[BSA] (1-methyl-2-pyrrolidinonium benzenesulfonate) + LaCl₃ + H₂O, and [NMP]­[p-TSA] (1-methyl-2-pyrrolidinonium p-toluenesulfonate) + LaCl₃ + H₂O and their binary subsystems LaCl₃ + H₂O, [NMP]­[MSA] + H₂O, [NMP]­[BSA] + H₂O, and [NMP]­[p-TSA] + H₂O. The densities and viscosities of the ternary systems are estimated using the literature equations and the corresponding properties of their binary subsystems. The comparisons of the predicted and the measured results are made.
